6 Claims.

This inventicnrelates to heating and ventilatapparatus for motor vehicles and more particularly to air distributor means therefor.

Broadly the inventioncomprehends the. provi sion of; an. air distributor adapted to be assoctated: with combination heating and; ventilating apparatus for motor vehicles for efiiectively and uniformly distributing air delivered thereto into the passenger compartment-oithe motor vehicle.

Anobject of theinvention is the provision of an air distributor means for heating and ventilatnparatus. of: simple and economical constrllotiio ffectivetoevenly and: silently distribw ute air; delivered thereto into the passenger CO1- per n t: Of; a. motor vehicle Within which. it is adapted to be located.

Another object, of the invention is the provision ofgair distributormeans for ventilating and heat -g apparatus for smoothly, uniformly, and q etly; distributinga high; volume of: air delivered t1 reto from the air impellerrneans of. the ventilating and heating apparatus.

A further object or the invention is the pros visionof an air distributor means icr ventilating and heating apparatus for evenly and; effectively, distributing air delivered thereto over a, Wide area.

rivet further-object of the invention is'the provisionof air distributor means for distributing air delivered thereto-from an air impeller or blower of a heating ventilating apparatus of, motor vehicles having, means incorporated therein ef fective to nuimize the sound of air delivered thereto and distributed thereby.

A stillfurther object, of the invent-ion is; the provision of heating and ventila ng apparatus for motor-vehiclescomprising a; blower, a heating core, and an air distributing-housing associated. the blower and coreeffective to, distribute the. air delivered byethe blower-over a wide area with. a n 'nimum. of: air noise.

It has become necessary to provide in. association with presently developed high air capacity output heating and ventilating apparatus for motor vehicles air distributing and silencing means for delivering air to the passenger conipartment in a silent eirectivemanner. The present invention comprehends an airdistributing means in the form of housing of novel construction having sound: absorbing characteristics and air directing means foruniformly and silently distributing air delivered; thereto by air impelling means associated; therewith forming. part of a complete heating and, ventilating apparatus;

Referring-tome drawingsgfor. more specific de tails of the invention wherein like numerals. refer to like parts throughout the drawings; and. with referenceito-Eigure 1 thereof, ill; represents. gen-- erally; an: air distributor means; adapted to, form part of a complete heating: and ventilating apparatus-and adapted to be mounted in a suitable place inthe passenger-compartment of: the automotive vehicle for the deliverance of air to the passenger compartment thereof.

The air distributor it comprises a main body portion orhousing 12- having side wallsv i i and an singularly disposed top Wall is; said wallsand topbeing internally covered by a-sound absorbent sheathing is. An open end as of the housing is suitably secured to an air impeller housing said housing 22- being adapted to-receive therein anair impeller or, blower, not shown, for thepurpose of providing means for delivering air directly to the air distributing housing ii;

The housing;v 5-2;. is; also provided with a base opening 24 communicating with and having secured thereupon a heater core housing 2 5; in which is disposed; a-heater core 28, said core havingsuita-ble inlet and outlet connections to; and respectively for association with a heated liquid supply'such as the conventional cooling water; system of an, internalgcombustion engine of a motor vehicle. The core housing 28 has mountediin an opening Mathereof oppositely disposed from the opening it of the housing 52 communicating therewith an outlet conduit of Ventur-i or tapered cross sectional outline providing angularly disposedwalls 38- and to and having an opening s2 across the full face thereof serving as the outlet for air-delivered to the air distributor housing i2 from the air impeller or ls er adap ed tobe-mounted inthe housing 22-.

The conduit similarly to the housing i2 has a sound absorbent sheathing ad covering the internal faces of the walls 33 and A gate 46 hinged upon the wall 3% adapted to direct the outflow of air from opening 52 is tensionecl by spring 48 and includes a finger tip handle 59 permitting of the manual setting of the gate to the position desired of the full or dotted line positions as shown by Fig. 3 providing for directed flow of air. The wall is has a pair of apertures 52 and 5 associated with air defroster tubes 55 and 53 respectively controlled by a gate es mounted on the wall operable by a rod or cable 62 adapted to be manually manipulated from a point remote from the distributor.

Figure 2 is a modified form of air distributor of similar design as that shown by Figure 1 with the omission of the heater core and heater core housing such that the outlet conduit Si is directly mounted upon the housing i2 thus providing that the air delivered to the housin i2 is directly distributed therefrom through the conduit 36 to the passenger compartment. In a structure of this sort with the distributor associated with aheating system as well as providing use as a ventilating system for the distribution of air the heater core therefor may be arranged at a point in the heating apparatus forward of the air impelling housing so as topermit of the function of the air distributor, as shown by Figure 2, in a like purpose and capacity as the structure shown by Figure 1.

While this invention has been described in connection with certain specific embodiments, the

principle involved is susceptible of numerous other applications that will readily occur to persons skilled in the art. The invention, therefore, is limited only as indicated by the scope of the appended claims.
